Okay let's just start saying that the classes in shaiya mercury are not balanced at all, mostly because of debuff lapises.I'll explain better: assassins/rangers have only 4 sec to perform a combo,a pretty ridicolous amount of time since you'll spent most of it dispelling stun debuff and thus loosing the chance to perform the whole chain combo. The same things can be told about archers/hunters who keep running away preventing the sin from using his combo and the latter has to use the chain all again from the beginning(this always result in sin death)...so my suggestion is to remove chain so that people who want to play this class won't be forced to leave it in order to create another toon with another class. And I know that chain are assassin's and ranger's main feature but it is an handicap in retroservers like this one that, beside this "issue" that doesn't make all classes playable in the same way, is really amazing...
